There are only two firms in an industry with demand curves q1 = 30 - P and q2 = 30 - P. Both have no fixed costs and each has a marginal cost of 10 per unit produced. If they behave as profit-maximizing price takers, each produces 10 units and sells them at a price of 10 so that each firm makes zero economic profits. If they form a cartel, their inverse demand curve is
A) Q = 30 - P. B) Q = 60 - 2P. C) P = 60 - 2Q. D) P = 30 - Q/2.
Cal has a choice between two gambles. The first gamble offers a 50 percent chance of winning $20 and a 50 percent chance of losing $20. The second gamble offers a 20 percent chance of winning $100 and an 80% chance of losing $20. Which choice has the higher expected value?
